DANIEL J. WOLFE, OF GILROY, CALIFORNIA.

HAY-PRESS.

To all whom it may concern:

Be it known that I, DANIEL J. WOLFE, a citizen of the United States, residing at Gilroy, in the county of Santa Clara and State of California, have invented a new and useful Hay-Press; and I do hereby declare the following to be a full,'clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same.

This invention relates to a new and useful hay press adapted for baling hay and the like and discharging it from the upper portion, the baling chamber being fed below.

The principal object of the invention is the provision of a baling chamber through which more than one bale is being forced while baling, so that as a lowermost bale is being raised in position to be bound with Wire, an uppermost bale is being discharged.

It is a further.object of the invention to provide a plunger for packing the hay in bales and a cut-off door actuated by the plunger for cutting off the feed. I

Another object of the invention is the provision of a locking device actuated automatically by the plunger for locking the door, and then automatically actuated by the plunger on a further movement thereof to release the door,

It is the aim of the invention to devise a hay press of this nature, in which various improved, essential, eflicient and desirable features of construction are involved.

One of the features of the construction resides in a plurality of needles adapted to be fed transversely of the bale chamber, all at the same time and through transverse grooves of the follower, for drawing the baling wire finally about the bale, so that a portion may be gripped by clamps, while, at the same time, another portion is being severed and the two ends of the wire about the bale are being tied.

The invention comprises further features and combinations of parts, as hereinafter set forth, shown and claimed.

In the drawings, Figure 1 is a view in side elevation, showing the improved hay press constructed in accordance with the invention. Fig. 2 is a vertical sectional View. Fig. 3 is a sectional view on line 33 of Fig. 1, showing the plurality of nee dles. Fig. 4 is a detail View in side elevation, showing the locking mechanism for Specification of Letters Patent.

the door, showing in full lines the position of the locking mechanism prior to being actuated by the plunger to lock the door. Fig. 5 is a view similar to Fig. 1, showing the locking mechanism after having been actuated by the plunger. Fig. 6 is an en larged detail view of the piercing end of one of the needles. Fig. 7 is a rear view of the press, showing the manner in which the needles are actuated. Fig. 8 is a view in elevation of the clamps and the severing devices. Fig. 9 is a plan view partly in section of the clamps and the severing devices. Fig. 10 is a fragmentary view of the frame carrying the needles, showing the means for shifting the same.

Referring to the drawings, 1 designates the frame of the hay press, the main portion of which is provided with a baling chamber 2. The supplemental frame 3 receives the plunger 4, there being guides 5, in which extensions 6 of the plunger are guided. The plunger is provided with a plunger bar 7 which may be actuated by any suitable means, preferably horse-power. However, a suitable engine may be substituted therefor. The plunger is braced relatively to the plunger bar by the braces 8. Extending upwardly from the supplemental frame is an offset chute 9, in which the door 10 is arranged, for cutting off the feed of the hay. This door is hingedly connected, as at 11, to the plunger. As the plunger is forced through the supplemental frame, the door 10 is actuated to close the passage 12 between the chute and the supplemental frame.

Secured to the supplemental frame, as at 13 and 141, is a pair of bars 15, which are connected, as at 16. Also pivoted at the point 16 is a lever 17, one upon each side of the supplemental frame. These levers 17 have link connections 18 with two of the extensions 6 of the plunger, whereby, as the Fixed to one end of the rod 22 is a pawl 23, to the free end of which a spring 24 is connected. The end 25 of the spring is fixe'd at the point 26 to the side of the chute 9.

Pivoted at 27 to one side of the supple mental frame is a lever 28, having a shoulder 29, which is engaged by the pawl 23. A spring 30 fixed at 31 to the supplemental. frame bears against the lever 28 and holds the shoulder in engagement with the pawl 23. The normal positions of these parts are as shown in Fig. 1. As the plunger moves forwardly of the supplemental frame, a portion of the extension 6 strikes the end 32 of the lever 33 pivoted at 34 and actuates the rod 35, which is pivoted to the upper end of the lever 33. The rod 35 is mounted in a guide 36. hen the rod 35 is actuated, the rear end thereof engages the lever 28, thereby disengaging the shoulder thereof from the pawl 23, against the action of the spring 30. When the pawl 23 is thus released, the spring 24 actuates the pawl to the position, as shown in Fig. 4 and as the latch locking dogs 2]. are carried by the rod 22, the noses 38 of the dogs are thrown from the path of the door 10, so that the door will open as the plunger moves rearwardly of the supplemental frame. As the plunger reaches its rearward position, it contacts with the arms 39 of the dogs 21, thereby rocking them, and also the rod 22. By virtue of this action, the pawl 21 is again thrown inengagement with the shoulder 29 of the lever 28, thus holding the dogs 21 in the positions shown in Fig. 1. As the door 10 moves to a closed position, the rear upper end thereof passes over the noses 38 of the dogs 21, thereby locking the same closed, until the plunger moves rearwardly.

The object of the locking dog 21 is to hold the door 10 locked in position, and furthermore in case the plunger 4 is accidentally moved rearwardly before its time for such movement, the locking dogs 21 will tend to retard such movement. Referring to Fig. 1 of the drawings the rod 35 has not been operated to engage the lever 28, so as to disengage it from the pawl 23, and these actions will not take place, until the plunger 4 is moved farther forwardly, than thatshown in Figs. 1 and 2.

Mounted vertically movable in the baling chamber is a follower 40, each end of which is provided with an extension 41. The extensions 41 are mounted in guides 42 of the frame 1. The follower 40 is provided with a plurality of transverse grooves 43, through which the needles 44 extend. The follower is raised vertically in the baling chamber by the lever 45, which is actuated by the means 46.

Projecting laterally from the upper portion of the frame 1 is a platform 47 braced by the bars 48. This platform is for the purpose of holding the operator at the top of the machine, whereby he may receive the bales as they are discharged. After each bale is discharged from the chamber of the frame 1, it is allowed to slide down the bale slide 49. Below the platform, and secured to the sides of the frame 1, is a pair of bracket members 50. Journaled in the bracket members 50 is a shaft 51, on which is mounted a plurality of reels 52 containing baling wire 53. The wires of the various reels pass under the pulleys 54, and upon first operating the machine, the ends of the wires are manually extended transversely of the upper portion of the baling chamber, as at 55, and are caught by the clamps 56 and 59 as shown in Fig. 9. As a bale is formed in the bale chamber 2, and subsequently forced upwardly in the chamber, the various wires are arranged about two sides and the upper end of the bale. At this period, the needles 44 are operated by the operator upon the platform 47, so as to move transversely of the frame 1, and through the transverse grooves 43. When the needles reach the limit of their transverse movement across the frame 1, the wires assume positions behind the pulleys 58 of the needles. The needles are then withdrawn from transversely of the frame 1 and with them the wires. In this manner, the wires are drawn around the lower end of each bale. As the needle points reach their rearward positions, portions of the wires are caught by the other clamps 59 and the clamps 59*, while other portions are severed by the cutting edges 60 of the clamps 59 The clamps 56, 59, and 59 are pivoted at 59 to the strip 59 which is arranged in a fixed position transversely of the needles. To one end of the strip 59 a lever 60 is pivoted, which is adapted to have the usual grip actuated dog (not shown), to engage the teeth of the rack 60 to hold the lever in adjusted positions. The lever 6O is pivoted at 60 to the strip 59 while the lower end of the lever is piv-' oted at 60 to the strip 60 to which the clamps 59 are pivoted at 59 Then the lever 60 is operated, the strip 60 is moved in a direction transversely of the needle, thus throwing the upper ends of the clamps 59 toward one or the other of the clamps 56 and 59, in order to catch the wire. As soon as the wire is caught it is instantly severed thereafter by the cutting edges 60. These clamps are actuated by the operator on the platform 47. The wires about the bale are then twisted by another operator. The wires which are caught by the clamps and designated by the numeral 61, support the bale which has been bound, so that the follower may be lowered to receive the next bale from the supplemental frame.

The needles 44 are carried by a frame 63,

each end of which is formed with a triangular frame 64. The triangular frames 64 of the frame 63 have anti-frictional wheels 64, between which the guides (which are secured at 66 to the frame 1) of the frame 65 are guided, thereby avoiding undue friction.

Pivoted at 67 to the frame 65 is a lever 68, the curved edge 69 at the free end of the lever contacting with a roller 70 on the frame 68, so to operate the frame to withdraw the needles from the frame 1. To cause the needles to move through the frame 1, the lever 68 contacts with the roller 72. A lever 73 pivoted at 74 to the frame 1 is connected, as at 75, to the lever 68. The operator, by manipulating the lever 73, may actuate the frame 63 to extend the needles through or withdraw them from the frame 1. The frame 65 is braced by the bars 77.

The end of each needle is provided with a strap 7 9 to guide the wire behind the pulley 58, while an additional metal strap 80 is secured in the rear of the pulley 58, so as to prevent displacement of the wire. The strap 80 not only prevents displacement of the wire, but keeps the hay from becoming clogged about the pulley 58.

The chute is fed by means of a draper or endless elevator 81.

When the chute is fed, the plunger is in a rearward position. The hay falls in front of the plunger. When there is a sufficient amount of hay to form a bale, the plunger is moved forward of the supplemental frame, by a pulling action upon the cable 19. As the plunger moves forward, the rear end of the door 10 slides over the noses 38 of the dogs 21, thus holding the same closed. By this movement of the plunger, the hay forming the bale is forced into the bale chamber upon the follower. The plunger is permitted to move a trifle farther, which thoroughly packs the bale. By this further movement, the extension 6 of the plunger actuates the lever 33, which, in turn, reciprocates the bar 35. This bar 35 actuates the lever 28, thus releasing the pawl 23 from engagement with the shoulder 29 of the lever 28. As the pawl 23 is released, the spring 24 throws the noses 38 of the dogs 21 from the path of the rear end of the door 10, so that the same may assume the position shown in Figs. 1, 2, 4, and 5, upon the rearward movement of the plunger. However, prior to moving the plunger rearwardly, after the bale is forced into the chamber 2, the follower is elevated, and with it the bale. The bale is raised until its lower end reaches a distance slightly above the plane of the needles 44. The needles 44 are then moved through the grooves 43 of the follower so as to engage the wires. Subsequently, the needles are withdrawn, bringing the wires with them, which are clamped by the clamps and then severed. At this period, the follower is lowered, and, at the same time, the plunger is moved rearwardly, Each of the consecutive bales is formed, bound and tied, and finally discharged in a similar manner.

From the foregoing, it will be noted that there has been devised an efficient, practical and desirable hay press, and one which will economize on space and labor, and, at the same time, bale more percentage of hay than the average press now in the field.
